y w, W25. 2 5mm J. AFYAEEFZ'RTQLJ CAN MARKING MACHINE Filed Jan. 19,1924' :s Shee Anew/EM time and labor is provided for the packer. As a.certain grade of fruit is picked up, the

cans as marked and delivered from one end cf the mechanism will be used,and as an other grade of fruit is picked up it is packed in differentlymarked cans taken from the other end of the mechanism. Various systemsand methods of marking and handling the cans, depending on the fruit athand and marking mechanisms for difi'erent marksv and then on eachoperation of the marking mechanisms, cause cans having different marksto be delivered at spaced but accessible I points near him.

The mechanisms 4 and 5 are identically constructed and each comprises ashaft 9 which is journaled in and extends between the plates 1. Thisshaft supports a plurality of marking rollers 10 and a special markingroller 11. Each of the rollers 10 is provided with a slot 12 providingfor movement of the rollers into and out of marking position, and forremoval of the rollers from the shaft. The shaft carries projections 13which are adapted to engage in sockets 14 formed in the rollers at theinner ends of the slots 12, in order to provide for rotation of therollers on turning of the shaft. To releasably hold the rollers inoperative posi-' tion on the shaft, there 'are provided spring urgedfriction balls 15 adapted to. engage the shaft as shown in Fig. 6. Theseballs are fitted in openings on opposed sides'of the slot and are urgedoutwardly by spr ngs 16 so that they set up sufficient friction. tomaintain the rollers in place but will yield and permit the rollers tobe moved out of marking position orofl of the shaft. The peripheries ofthe r'ollers are formed with grooves 17 in which are mounted markingstrips 18 being secured by suitable fastenings 19 adjacent the terminalsthereof, which terminals are disposed on opposite sides of the slots.These strips are preferably formed of rubber and are inked by an inkingroller '20. The roller ll is provided with a peripheral groove 21 inwhich marking dies 22 may be mounted. The dies make marks which identifythe packer or date the cans, or make any other designations that maybenecessary. On this roller there mounted a rubber friction ring'23 whichis adapted to engage thecans discharged between the plates 1 and tocausethe cans to be moved downwardly into position to be marked when theshaft is rotated.

The rollers 10 are sub ect to being moved into and out of markingposition in order that marks may be madeat diil'erent levels or pointson the cans and there are pro vided arms 24 having circular, openings 25in certain ends, in which'openi-ngs are re ccived annular projections 26provided on the sides of the rollers. The projections 26 and the arms asare provided with slots corresponding to the ones in the rollers butwhich slots in the members 24 are closed at both ends. These arms 24vare provided intermediate their ends with slots 27 through which a rod28 extends in order to support said members, the rod being fas; tened toand between the plates. The outer ends of the arms 24 are pivoted'as at29 to the levers 30, which at their upper ends are pivoted on a rod 31supported by ex tensions 32 of the plate ll The levers are of differentlengths so 4 rollers be readily pulling out one ofthe love: an arm 24:is pulled outwardly causi L) the roller to which itis attached to bcorrespondingly moved and be disposed. in non-marking position.

Just below the'oppcsite ends of the chutes 7 and 8 there is provided aguide member 33 which is yieldingly forced towards the marking rollersby a spring mounting ar- 'rangement, generally designated 24. the cansdischarge from the chutes '2 and. between the plates, they are engagedbetween the yielding guide and the rubber ring n guished. On

on the roller 11. On rotrdzingthe shaft the cans are forced downwardlyby said'rubber ring and are guided forwardly at the same time by theyielding guide 33, so that they will come in contact with the rollerswhich ,1. the different happen to be in marking position. Engagement ofti ie cams with the marking, rollers cause the cans to be rotated sothat they are advanced and will drop From between the guides and rollersout onto the table, or as shown, through the small discharge chute 35.The shaft has a gear ififixed to one end thereof. which gear meshes,with a drive gear '37 mounted on one of the plates of the frame. on oneside of the gear 37 is a- 3 disk 38 to which a handle 39 is attached.The disk 38 is provided with a notch or shoulder 39 which is engaged bya spring urged pawl or a detent it), the arrangement beingsuch that thispawl prevents rotation or the disk In one direction.
